Conundrum is one of the labels produced by Wagner Family of Wine, an umbrella company for a portfolio of family-produced wines, the most famous of which is Caymus. Conundrum introduced its first wine, a white blend called Conundrum White, in 1989. Conundrum now also makes a red blend, a rosé and a sparkling wine. Chuck Wagner, current patriarch of the Wagner family, descends from Alsatian immigrants who settled in Rutherford in 1906 and produced bulk wines until Prohibition. Several generations later in 1972 the family established Caymus Vineyards, widely recognized as one of Napa’s finest producers. Today Chuck Wagner’s adult children are also involved in the family’s wine enterprise, which includes the labels Red Schooner, Mer Soleil and Emmolo.
